As a result of Olympia's growing population, the government created the Washington Territory.
In 1846, Edmund Sylvester and Levi Smith claimed the territory that now corresponds to the city center. In 1851, the US Congress established a customs for the northern area of Oregon in the Puget Sound, becoming this city in the center of customs. The population began to grow thanks to the numerous immigrants who followed the path of Oregon. As early as 1853, with the creation of the Washington Territory as a result of the increasing population, the city officially became known as Olympia.
